GSM900 and DCS1800/PCS1900  
Dual-Band, Low-Noise Amplifiers  
General Description  
Features  
The MAX2651/MAX2652/MAX2653 silicon germanium  
(SiGe), low-noise amplifiers (LNAs) are intended for use  
in GSM900, DCS1800, and PCS1900 band wireless  
handsets. The MAX2651/MAX2652 consist of two LNAs,  
one optimized for the GSM900 band and the other opti-  
mized for the DCS1800/PCS1900 bands. They feature a  
band-select pin to switch between the two LNAs, as well  
as a gain-step input to reduce the gain of each LNA by  
20dB and reduce supply current. The MAX2652 is func-  
tionally equivalent to the MAX2651, but features a low-  
power shutdown mode. The MAX2653 consists of a  
single LNA optimized for the DCS1800 and PCS1900  
bands, and has a shutdown feature and a 20dB gain  
step.  
ꢀ Wide Operating Frequency Range  
800MHz to 1000MHz (MAX2651/52)  
1800MHz to 2000MHz (MAX2651/52/53)  
ꢀ Excellent Low-Noise Performance  
1.2dB/1.3dB over GSM Receive Band  
(MAX2651/52)  
1.8dB/1.8dB/1.7dB over DCS Receive Band  
(MAX2651/52/53)  
ꢀ High Gain  
18dB over GSM Receive Band (MAX2651/52)  
18dB/17.5dB/18.5dB over DCS Receive Band  
(MAX2651/52/53)  
The MAX2652 and MAX2653 together form an ideal  
solution for triple-band phone applications (GSM, DCS,  
and PCS bands).  
ꢀ 20dB Gain Reduction in Low-Gain Mode  
ꢀ Externally Adjustable Gain  
ꢀ +2.7V to +3.3V Single-Supply Operation  
The MAX2651/MAX2652/MAX2653 are fabricated using  
an advanced high-frequency SiGe bipolar process. As  
a result, all devices provide low noise figure, high gain,  
and high input third-order intercept point (IP3) perfor-  
mance at the GSM, DCS, and PCS bands. A pull-up  
ꢀ Low Supply Current  
5.4mA to 7.0mA in High-Gain Mode  
2.2mA in Low-Gain Mode  
ꢀ 0.25µA Shutdown Current (MAX2652/53)  
resistor to V  
at each LNA output allows for gain  
CC  
adjustability. A minimal number of external components  
are needed for input and output matching, helping to  
reduce board space.  
Ordering Information  
The MAX2651/MAX2652 are packaged in a 10-pin µMAX,  
while the MAX2653 is packaged in an 8-pin µMAX. All  
devices operate from a single +2.7V to +3.3V supply.
